Most companies would like to reduce costs of providing goods and services while the government and society are pushing for more “green” practices. By developing an energy management plan, a company can find a systematic way to reduce energy usage and operating costs at the same time. This article presents a six-sigma based energy management planning procedure, focusing on five major steps: define, measure, analyze, improve, and control. An overview of the major energy-consuming equipment in manufacturing industries is provided. Different energy-saving opportunities are then investigated. The results from this research provide information and a clear understanding for establishing an energy management plan, which can be used as part of the ISO 50001 implementation.
